– UV-IR Cut Off Filters

Longpass Filters transmit wavelengths greater than the cut-on wavelength, while Shortpass Filters transmit wave-  lengths shorter than the cut-off wavelength. Dichroic filters perform the same function, while guaranteeing that the  rejected wavelengths are reflected. Any of these filters can be designed for 0  or 45  angle of incidence. Edge and Di- chroic Filters are commonly used in Fluorescence instrumentation, Heat Rejection Applications, and as Color Filters.  While somewhat angle sensitive, they are more forgiving than bandpass
